Solar and batteries are cheap enough that most people can get most of their electricity from them, and save money. This equation gets better and better over time as their costs decline. All details in a new blog post: nworbmot.org/blog/solar-b...

How individual systems and their connections react to each other to ensure stability of the whole.
We live in a complex world with a plethora of connections and interactions. Many important processes, such as power grid dynamics, ecological interactions, opinion formation, or brain plasticity, can ...

As the hydrogen bubble deflates, what are the alternatives? We present a "minimal methanol economy": using methanol as a gap-filler for the few sectors electrification can't reach. New working paper together with Philipp Glaum, @fneum.bsky.social, @millinger.bsky.social: arxiv.org/abs/2505.09277

OK, this is wild. In September 2023, geophysicists across the world started monitoring a very odd signal coming from the ground under them. It was picked up in the Arctic. And Antarctica. It was detected everywhere, every 90 seconds, as regular as a metronome, for *nine days*. What the HELL? 1/
